Description

Technical Field

[0001] The utility model belongs to the technical field of automobile power battery safety, and more specifically, relates to an automobile high-voltage wire plug connector protection structure and an automobile. Background Art

[0002] Electrical safety is a critical performance characteristic of electric vehicles. To meet long driving range requirements, electric vehicles often feature large battery packs, placing high-voltage cable connectors relatively close to the front engine compartment. During a head-on collision, high-voltage cable connectors can easily be squeezed, break, and come into contact with the vehicle, generating sparks and posing a fire risk. Even if the power battery power-off protection function is activated during a collision, residual charge in the high-voltage cable can still generate sparks when in contact with the vehicle, posing a fire risk. Therefore, collision protection for high-voltage cable connectors is particularly important.

[0003] Typically, a frame-shaped subframe is used in vehicle design to protect high-voltage cable connectors and the power battery from the front. However, due to platform-based design, hybrid and range-extended vehicles lack the necessary space for the engine, motor, and other components in the front cabin, making it difficult to design an effective frame structure and thus providing adequate high-voltage cable protection. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the existing technology and provide a protective structure for a high-voltage wire connector of an automobile and an automobile. The structure utilizes the existing structure of the battery frame and adds a protective bracket to wrap the high-voltage wire connector as a whole, effectively blocking the extrusion of the subframe, engine suspension and other structures in a frontal collision of the automobile, effectively protecting the connector from extrusion failure and breakage, and at the same time reducing the extrusion of the battery pack.

[0005] In order to achieve the above-mentioned object, the utility model provides a protective structure for a high-voltage wire connector of an automobile, comprising:

[0006] The protective bracket is arranged on one side of the high-voltage wire connector close to the battery pack, the protective bracket is connected to the battery frame, and the protective bracket surrounds the outer periphery of the high-voltage wire connector.

[0024] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0025] The utility model provides a protective structure for a high-voltage wire connector for an automobile, comprising:

[0026] The protective bracket is arranged on one side of the high-voltage wire connector close to the battery pack, the protective bracket is connected to the battery frame, and the protective bracket surrounds the outer periphery of the high-voltage wire connector.

[0027] Specifically, a protective bracket is added to the original battery frame, which is fixedly connected to the battery frame. The protective bracket also wraps and protects the high-voltage wire connector to prevent the deformation of the car body structure from squeezing the high-voltage wire connector during a car collision, thereby causing residual charge to come into contact with the car body and generate electric sparks.

[0028] Optionally, the protective bracket is C-shaped, and both ends of the protective bracket are connected to the battery frame.

[0029] Specifically, the protective bracket is set in a C shape and is made of cast aluminum. The protective bracket is connected to the battery frame at both ends. The space enclosed by the protective bracket and the battery frame can just enclose the high-voltage line plug connector, preventing the external structure from exerting external force on the high-voltage line plug connector and causing damage to the high-voltage line plug connector.

[0030] Optionally, both ends of the protective bracket are connected to the battery frame through connecting pieces, and the plane where the connecting pieces are located is perpendicular to the X-axis.

[0031] Optionally, the connecting piece is fitted with the battery frame.

[0032] Optionally, the connecting piece and the battery frame are connected by bolts.

[0033] Specifically, a connecting piece is provided at the end of the protective bracket, and the connecting piece is fitted and fixed to the X-direction plane of the battery frame, so that the protective bracket can be effectively supported in the X-direction, and the protective bracket is connected to the battery frame with bolts. In this way, after the protective bracket is deformed under pressure, the protective bracket can be replaced separately without damaging the battery pack, thereby avoiding greater economic losses and fire risks in the collision; when a car collides, the collision force is generally transmitted along the X-direction. When the protective bracket is subjected to the collision force, the connecting piece is fitted and connected to the battery frame, thus forming an X-direction force transmission path, thereby transmitting the collision force to the battery frame, decomposing the force, and avoiding compression damage to the high-voltage line connector.

[0034] Optionally, the middle portion of the protective bracket is connected to the vehicle body via a connecting column, and the axial direction of the connecting column is parallel to the Z axis.

[0035] Optionally, at least two connecting columns are provided, and the connecting columns are connected to the vehicle body by bolts.

[0036] Optionally, the protective bracket is arranged in alignment with the high-voltage line connector.

[0037] Specifically, in addition to being connected to the battery frame, the protective bracket is also connected to the vehicle body. However, the protective bracket is fitted and connected to the X-direction plane of the battery frame through a connecting piece, and the protective bracket is fitted and connected to the Z-direction bottom surface of the vehicle body through a connecting column. This can increase the fixing strength of the protective bracket, so that it can withstand more collision force.

[0038] The utility model also provides an automobile, comprising the above-mentioned automobile high-voltage wire plug connector protection structure.

[0039] Optionally, the high-voltage wire connector is arranged on a side of the battery pack close to the stabilizer bar and the subframe.

[0040] Specifically, the high-voltage wire connector is generally set on the side of the battery pack close to the front of the vehicle, and in the area between the subframe and the front floor of the vehicle body. In this way, one end of the high-voltage wire is connected to the battery pack and the other end is connected to the vehicle power system, reducing the setting length of the high-voltage wire and optimizing the layout of the vehicle chassis; when the front of the vehicle collides, the rear crossbeam of the subframe, the engine suspension and other structures are squeezed, and the generated frontal collision force is first transmitted to the protective bracket. Due to the installation method of the protective bracket, the frontal collision force is transmitted to the battery frame and the vehicle body through the protective bracket, effectively protecting the connector from extrusion failure and breakage, while reducing the extrusion of the battery pack.

[0041] Example

[0042] like Figures 1 to 3 As shown, the utility model provides a protective structure for a high-voltage wire connector for an automobile, comprising:

[0043] The protective bracket 1 is arranged on one side of the high-voltage wire connector 3 close to the battery pack. The protective bracket 1 is connected to the battery frame 2 and surrounds the outer periphery of the high-voltage wire connector 3.

[0044] In this embodiment, the protective bracket 1 is C-shaped, and both ends of the protective bracket 1 are connected to the battery frame 2 .

[0045] In this embodiment, both ends of the protective bracket 1 are connected to the battery frame 2 via connecting pieces 4 , and the plane where the connecting pieces 4 are located is perpendicular to the X-axis.

[0046] In this embodiment, the connecting piece 4 is in contact with the battery frame 2 .

[0047] In this embodiment, the connecting piece 4 and the battery frame 2 are connected by bolts.

[0048] In this embodiment, the middle portion of the protective bracket 1 is connected to the vehicle body 8 via a connecting column 5 , and the axial direction of the connecting column 5 is parallel to the Z axis.

[0049] In this embodiment, at least two connecting columns 5 are provided, and the connecting columns 5 are connected to the vehicle body 8 by bolts.

[0050] In this embodiment, the protective bracket 1 and the high-voltage line plug connector 3 are arranged in alignment.

[0051] The utility model also provides an automobile, comprising the above-mentioned automobile high-voltage wire plug connector protection structure.

[0052] In this embodiment, the high-voltage wire connector 3 is arranged on a side of the battery pack close to the stabilizer bar 6 and the subframe 7 .

[0053] In summary, the protective bracket 1 is installed in front of the battery frame 2, so that the protective bracket 1 can surround the high-voltage wire connector 3. When the front of the car collides, the front stabilizer bar 6, subframe 7 and exhaust pipe 9 will move towards the battery pack after being deformed by force. At this time, the protective bracket 1 can contact the parts that deform backwards and transfer the collision force to the battery frame 2, thereby preventing the high-voltage wire connector 3 from being damaged.

[0054] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
